In one aspect of the present disclosure, a side bearing is provided for supporting a body of a rail car. The side bearing includes a base for being mounted to a truck of the rail car, a support configured to contact the body of the rail car and move along a vertical axis relative to the base with movement of the body, and at least one resilient foam member configured to deform with movement of the support. The side bearing further includes at least one friction damping member configured to be urged in a direction transverse to the vertical axis against the base by the support and resist movement of the support relative to the base.

A railcar truck and adapter pad system for placement between a roller bearing and side frame pedestal roof of a three-piece railcar truck. Many different features of the pad and/or the adapter-pad interface are configured to improve stiffness characteristics to satisfy both curving and high speed performance of the railcar truck.

A device including a running roller (2) which can be rotated about a rotational axis (10), for a conveyor system, and a suspension system which supports the running roller (2) and has a fork (6) and an axle pin (7) which penetrates the running roller (2) and is supported by the fork (6). The suspension system has, furthermore, a first and a second clip part (8) which have in each case a recess (8a), into which a respective one of the end sections (7a, 7b) of the axle pin (7) protrudes The first and a second clip parts (8), for connection to the fork (6), can be pushed in each case in a push-in direction (13) which lies at a right angle with respect to the rotational axis (10) into a respective push-in track (6d) of the fork (6) and can be snapped together with the fork (6).

A railcar adapter for radially connecting a railcar body to a bearing. The railcar adapter includes an adapter body, and a top cover mounted onto an outer surface of the adapter body. The top cover is provided with at least one curved outer surface to be in direct radial contact with the railcar body.
